Question

14.4.2 test (cst): data and mathematical modeling
which of the following best approximates the line of best fit?

Explanation:

A line of best fit should pass through the middle of the data points, showing the general trend. Option A is a horizontal line which doesn't follow the upward trend of the data. Option B has a steeper slope and doesn't balance the points above and below as well as Option C. Option D also doesn't center the points as effectively as Option C. Option C is positioned such that there are approximately equal numbers of data points above and below the line, which is a key characteristic of a good line of best fit.

Answer:

C.
